This algorithm is used to reduce thecomputation time and complexity that occur in Estimation of Signal Parametersvia Rotational Invariance Technique (ESPRIT). In order to illustrate the accuracyand flexibility of the proposed algorithm, several simulation cases introduce ofESPRIT-DOA estimation by using ACO algorithm in environment of Matlab 7.8program. Results are statistically analyzed in order to conclude from it thealgorithm's accuracy and reliability
